Duncan Overglazes consist of precious metals in metallics overglaze form and, when fired, yield the brilliance of gold and white gold, and lusters for a rainbow of hues, like that of a pearl.
Bright Gold, White Gold, premium Gold are are real precious metals applied to fired glazed ware as the final finish. Mother-of-Pearl is a translucent overglaze with a lustrous iridescence. Essence is a must-have cleaning solution for all of your brushes and tools used with Duncan Overglazes.
Metallics are opaque, with the brilliance of 22-karat yellow gold or white gold. The appearance of each metallic overglaze is determined by the glaze the metallic is applied over (ex. when applied over a gloss glaze, the metallic will be shiny; a matte glaze, the metallic will be dull). Metallic Overglazes are normally applied over a fired glaze but can also be applied to unglazed high-fired porcelain or stoneware bisque. If applied over unglazed porcelain and stoneware the appearance is extremely matte. For ease of application, each brush-on overglaze is tinted with its own special color. Premium Gold has a red tint, Bright Gold has a brown tint, and White Gold has a green tint.
Mother-of-Pearl is a metallic compound that is applied as a final finish over fired glazes that are compatible with overglazes. Mother of Pearl is a translucent overglaze with a lustrous iridescence, and creates an iridescent look when properly applied and fired. Its appearance is determined by the glaze that the luster is applied over (gloss glaze, shiny luster, matte glaze, dull luster). For ease of application, each brush-on overglaze is tinted with its own special color. Mother-of-Pearl has a blue tint.
OA 901 Essence is used to thin lusters, or re-wet dried out luster on brushes or inside the bottle. Other cleaning agents may contain water or solvents, resulting in the separation of overglaze during subsequent applications. You can clean brush in Essence and let dry, but it is wasteful to throw away gold. So when done lustering, wrap the brush in foil, when you need to use it a few drops of Essence will bring the luster back.
We’ve captured the timeless, iridescent beauty of precious gold and everyone’s favorite gemstone and transformed it into overglazes, ideal for making your work look like a million bucks.
Metallic Overglaze Application
Mother-of-Pearl Overglaze Application
Duncan Overglazes are non-toxic after firing. Work in a well-ventilated area when applying to your piece. Duncan Overgalzes are dinnerware safe but ware decorated with metallic overglazes should not be used in microwave ovens.
Overglazes can be used on surfaces that come into contact with food and drink. Care must be taken to avoid hard scrubbing when washing overglazed ware, because of the possibility of scraping off the thin layer of metal or luster. Treat your overglazed pieces as you would fine china. Although overglazed ware will take repeated washings in a dishwasher, the overglaze will eventually wear away.
